Northern royal albatross (Diomedea sanfordi) eggs and chicks were collected at Taiaroa Head from 1995 to 1998 by Department of Conservation staff. Frozen whole eggs and chicks were submitted to ESR for chemical analysis. The analysis quantified the levels of polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), polychlorinated biphenyls (PCBs) and a range of persiste...

An attempt was made to rear the eri silkworm, Philosamia ricini on leaves of caster and reared under laboratory condition. It observed that is a primary potential host silkworm. The growth parameters cocoon characters silkworm were normal. successfully lasted its life cycle ranged from 38 40 days. effective rate rearing, weight pre-spinning larvae, cocoon, shell pupae 70 75 per cent, 6 7 g, 3.0...

Composite stiffened cylindrical shells are widely used as primary elements in aerospace structures. In the recent years, there has been a growing research interest in optimum design of composite stiffened cylindrical shell structures for stability under buckling load.  This paper focuses upon the development of an efficient optimization of ring-stringer stiffened cylindrical shell. The opti...

The research was conducted at Bangladesh Agricultural University Poultry Farm, Mymensingh to evaluate the effect of different levels and sources of calcium on egg production and egg shell quality of Japanese quail (Coturnix coturnix japonica) up to 23 weeks of age. For that purpose a total number of 108 Japanese quails aged 20 week were fed on diets containing different levels (2.5%, 2.75% and ...

The longevity of the population in the Okinawa Islands of Japan has been ascribed to genetic factors and the traditional Okinawa cuisine, which is low in calories and high in plant content. This diet includes shell ginger (Alpinia zerumbet (Pers.) B.L. Burtt & R.M. Sm) of the ginger family (Zingiberaceae). Due to its local popularity, Alpinia zerumbet has become the subject of a good deal o...

one hundred forty-four 26-wk-old white hy-line layers (w-36) were fed commercial diets containing 0, 1.5, 3 and 5% surplus date for three period of 28 days each to study the effects of dietary surplus date on hen performance (egg production, egg weight, egg mass, feed intake, feed conversion ratio ‘fcr’ and body weight gain) and egg quality parameters (haugh unit score, yolk colour index, yolk ...

the present study was carried out to investigate the effect of corn replacement by different levels of wheat with supplementation of phytase with reduced phosphorus level for laying hens. two hundred seventy nine layer hens (the strains of hy-line w36) at the 53th week of age, selected based on the same egg production percentage and body weight, assigned in a factorial arrangement with complete...

The article is devoted to the study of influence different modes LED lamps color temperature in high-speed lighting conditions 2C:5T:3C:2T:3C:9T on productivity and viability, quality cross "Shaver" hens’ eggs. 4 radiation were tested: 1st group-in all periods light 3000 K; 2nd group-the first last K, average period 5000 3rd group 4-the half each second K. It was found that groups 1, 2, 3 with ...

The genetic variation and diversity among fifty-eight polyvoltine silkworm genotypes was estimated by using ten economic traits. The results revealed that the single shell weight showed higher genetic variation such as PCV% (17.20%), GCV% (12.93%), and heritability (56.5%) followed by single cocoon weight, shell ratio and matured larval weight. The D2 (Mahalonobis? distance) statistics reveal...
